"Built to Amaze," the latest show by Ringling Bros. and Barnum & Bailey, is in the middle of a two-week run at NRG Stadium. The 143rd edition of the "Greatest Show on Earth" includes feats of strength, amazing acrobats and, of course, elephants.

It's all about "Wine, Cheese and Moths" at the Houston Arboretum. Limited to ages 12 and older, the event invites participants on an evening walk during which volunteers will use black lights to illuminate nocturnal flying insects. Refreshments will be served and a master naturalist will be available for questions.

Enjoy a leisurely pontoon-boat ride at Armand Bayou Nature Center. Pastries, juice and coffee will be served as a naturalist identifies plants and wildlife and discusses life on the bayou. Reservations required.
